The Evolution of Shotgun Design

by | Jan 22, 2021

In the gun trade, it is often said that there is nothing new. In theory, this is true as the concept of a gun firing is virtually the same as it was when the idea was very first thought of. Limitations in manufacturing prevented many well-thought-out ideas from coming to light. However, as styles of shooting continue to evolve and change so too does shotgun design and over the years shotguns have evolved to become what we know today.

A long time ago someone decided to fill a tube with gunpowder, put something solid on top, light the paper and fire. Starting the firearm revolution, shotguns have come a long way since their humble beginnings. On their journey, certain key components have impacted the evolution of shotguns more than others. These essential developments in shotgun design have led to the modern shotgun that most shooters are familiar with in the modern age.

Let’s take a look at some of the biggest influences on shotgun design that have helped to determine the evolution of the shotgun over time.

Gunpowder Beginnings

There are records of Chinese Alchemists making reference to a power that would ‘fly and dance’ in AD142. The powder was said to be made of three different substances, likely the basic ingredients of gunpowder, saltpetre, charcoal and sulphur. Used for many years for entertainment purposes or as a diversion, gunpowder was finally realised for its weaponry potential. The ‘fire lance’, a bamboo pole loaded with gun powder that propelled a flame at oncoming enemy soldiers, was the first recorded gun.

 

Trigger Evolution

While the trigger is often seen as a simple element of any weapon used to set off the gunpowder charge, it is in fact much more important. Without a trigger, it is not possible to aim a firearm as you would have to manually light a slow-burning fuse while trying to position the weapon. Triggers began as basic mechanisms that would lower a smouldering fuse into position to light the powder. However, spring-loaded mechanisms were soon introduced, evolving into the fire-pin and primer combination used in modern shotguns.

 

Introducing The Percussion Cap

Flint and steel were the go-to means of firing a weapon until fulminate of mercury was discovered. This volatile substance would ignite when it was struck with force, changing how a weapon could be fired. Reverend Alexander James Forsyth from Scotland developed a system where a hammer was used to detonate the fulminate of mercury, igniting the fulminate of mercury into a vent leading to the powder charge. This system was patented in 1807, giving birth to the percussion principle.

This system underwent many transformations over the years resulting in the percussion cap, a small copper hat with a detonating charge insider it, being developed. This was placed over a nipple and fired by a hammer. Established in the 1820s this was a major turning point in shotgun design, allowing for the creation of the all-in-one cartridge that we have today and the capacity to have a breech-loading shotgun design.

 

Breechloading Shotguns

Muzzle-loading shotguns had many limitations as they were slow and cumbersome to reload. In 1851, however, Frenchman Lefaucheux unveiled a new firearm design that would revolutionise shotgun design forever. Featuring hinged barrels a complete show, including shot power and an igniting gel could be loaded at the breech end of the weapon. It was fired with a hammer that struck a pin which protruded from the cartridge. The design was developed further and by 1871, the first hammerless gun was born, resulting in the base for the modern-day shotgun.

 

The Future Of Shotgun Design

As technology continues to improve, manufacturing processes develop and our knowledge of the science behind guns and shooting increases, the future looks exciting for shotguns. New materials and technologies could improve the shooting experience going forward, allowing for the development of guns that are easier to handle, operate and shoot with increased accuracy. Shotgun design will no doubt continue to evolve and it’s exciting to think what the future might hold.
